Description

Electric connection fixing structure of heating element

This creative department relates to a fixed structure of electric connection of heating elements of a heating machine.

With the rapid development of technology, the home appliance market has developed a heating machine in response to the low temperature in winter. The heating machine includes a heating element and a fan element, and the heating element uses a plurality of main heating elements of the heating element to generate heat to heat the wind blown by the fan element, thereby blowing out the heating and increasing the room temperature.

The prior art heating machine is mainly arranged with one or more main heating elements (generally PTC ceramics) arranged on a frame and energized to heat, so it is necessary to extend the design of the two wires of the positive and negative poles during manufacturing. A branch wire is extended to all parts of the frame body to be welded to each main heating element. In addition, in order to increase the heat-generating area to uniformly heat the wind blown by the fan assembly, the heating device in the prior art is provided with a plurality of heat dissipation fins (generally aluminum fins) on the main heating element, which can be The overall heat-generating area extends and expands, so that the heater in the prior art can use the heat-radiating fins to uniformly heat the wind blown by the fan assembly.

However, the prior art heater includes the following disadvantages:

First, due to the many changes in the form and design of the rack body, it is not easy to construct the welding procedure at some times, or too many branch wires have difficulties in routing and hiding, which leads to poor assembly and production; even a simple rack body The structure is convenient for wiring and welding, and will also increase the time and labor costs because each main heating element needs to be welded separately.

Second, because each main heating element is electrically connected to the power supply by wire welding, it is very inconvenient to repair when a fault occurs, and it takes a considerable amount of time and labor costs for both detection and troubleshooting; Moreover, if the main heating element itself is damaged, the main heating element cannot be replaced in time due to the structure of the cable welding.

Third, in order to reduce the manufacturing cost raised by wire welding, manufacturers of prior art heaters choose to reduce the number of main heating elements, and use heat dissipation fins to achieve the purpose of expanding the heating area, thereby uniformly heating the fan assembly. The wind blowing out. Although it seems to solve the problem of manufacturing cost, it has further derived other shortcomings, such as:

First, in order to avoid damage to the main heating element due to too slow heat dissipation, and at the same time, in order to make the temperature of all the heat dissipation fins uniform, the heat dissipation fins of the prior art must be designed so densely that the heat dissipation fins cannot If the spacing is too large, the air output will become very small due to the dense heat dissipation fins, which will lead to poor room temperature efficiency.

Second, in order to allow the heat dissipation fins to be heated to a certain temperature, the temperature of the main heating element will be very high, which may lead to a reduction in the service life of the main heating element due to long-term high temperature; and, After long-term use, the excessively high temperature may easily cause the heater to support the main heating element or other components connected to the main heating element to be damaged due to prolonged exposure to high temperature, and may even cause a fire.

To sum up, the existing heating device does need improvement.

In view of the aforementioned shortcomings and deficiencies of the prior art, the present invention provides an electrical connection fixing structure of heating elements, which is convenient for assembly and production, and does not require welding each heating element separately, so that the overall time and labor cost can be greatly reduced. Moreover, this creation can expand the heat-generating area without the need for heat-dissipating fins, so the disadvantages derived from the heat-dissipating fins can be avoided.

In order to achieve the above-mentioned creative purpose, the technical means adopted in this creation is to design an electrical connection fixing structure of the heating element, which includes: a frame body including a plurality of first accommodating grooves and a plurality of second accommodating grooves; Heating elements, the heating elements are respectively arranged in the first accommodating grooves, and the heating elements are respectively arranged in the second accommodating grooves; each of the heating elements comprises a first end and a second end And each of the heating elements is provided with the first end in the corresponding first accommodating groove, and with the second end in the corresponding second accommodating groove; a first conductive unit, which A plurality of first power receiving parts are arranged on the rack body, the first power receiving parts are electrically connected to each other, and the first power receiving parts are respectively penetrated in the first accommodating grooves of the rack body Each of the first electrical receiving parts abuts the first end of the heating element provided in the corresponding first accommodating groove, and is electrically connected to the heating element; a second conductive unit, which is provided A plurality of second power receiving parts are included on the rack body, the second power receiving parts are electrically connected to each other, and the second power receiving parts are respectively penetrated in the second accommodating grooves of the rack body Each of the second electrical receiving parts abuts against the second end of the heating element provided in the corresponding second accommodating groove, and is electrically connected to the heating element.

There is no need to design multiple extended branch wires as in the prior art. A conductive unit and a second conductive unit are connected to an external power source to enable all heating elements to generate electricity. In this way, the assembly only needs to place the electrical connection part and the heating element in the accommodating groove at the time of assembly and manufacturing, and does not need to solder the branch wires to each heating element one by one, which can save a lot of time in manufacturing The labor cost is also more convenient than the prior art during maintenance. If only a single heating element is damaged, the damaged heating element can be directly removed and replaced. Moreover, because the creation can have a low manufacturing cost that is incomparable with the prior art through the above-mentioned structure and effect, the creation can be achieved by directly increasing the number of heat-generating components without providing additional heat dissipation fins. The purpose of expanding the heating area; by this, since there is no need to conduct heat to the heat dissipation fins, each heating element of this creation can be operated at a temperature lower than the main heating element of the prior art, and the spacing between the individual heating elements can also be widened To an appropriate distance, the air output can be increased to improve the efficiency of raising the room temperature; in this way, this creation can avoid the derivative problems caused by the heat sink fins.
